RALPH R. REED, OF SAN FRANCISCO, CALIFORNIA.

CHAIR.

To all whom it may concern:

Be it known that I, RALPH R. REED, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements in Chairs;and I do declare the following to be a full, clear, and exactdescriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in self-leveling chairs.

One object of the invention is to provide a chair which is particularlyadapted for use on ships and having means whereby the same is alwayssupported in a level position irrespective of the rocking or rollingmotion of the vessel in any direction.

Another object of the invention is to provide a chair of this characterhaving means whereby the back and foot rest may be adjusted to differentangles.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claim.

In tie accompanying drawings, Figure l is a plan view of a chairconstructed in accordance with the invention; Fig. 2 is a sectional viewof a portion of a ships deck, showing a front view of the chair arrangedthereon and illustrating the operation of the chair when the ship isrolling sidewise; Fig. 3 is a vertical section through the center of thechair and a portion of the deck on the line 33 of Fig. 1; showing theposition of the parts when the ship is rocking endwise; Fig. 4 is a Viewsimilar to Fig. 3, showing the chair supporting devices in an uprightposition and the chair arranged as a reclining chair.

Referring more particularly to the drawings, 1 denotes the supportingbase which is adapted to be secured to the deck of a ship or othersupport in any suitable manner. Revolubly mounted on the base 1, is asupporting frame which comprises a semicircular or substantiallyU-shaped base engaging portion 2, on the upper end of which is secured ahorizontally disposed substantially circular chair receiving portion 3.A1- ranged within the upper portion or ring 3 are inner and intermediateconcentrically Specification of Letters Patent.

Serial No. 521,499.

arranged chair supporting rings or gimbals 4 and 5. The inner ring 4 ispivotally connected to the intermediate ring 5 by pivot pins 6 which arearranged therein, as shown. The intermediate ring 5 is pivotallyconnected to the outer ring or upper portion of the supporting frame 3by pivot pins 7 which are arranged at substantially right angles to thepins 6 which connect the inner and intermediate rings together.

Arranged in the inner supporting ring 4, is a chair or seat 8, the sideportions of which are secured to the ring 4 in any suitable manner. Theside portion of the chair 8 is preferably arranged below the level ofthe rings 4 and 5 and upper portion of the frame, as shown. The chair isprovided with an adjustable foot rest 9 and back 10, whereby the chairmay be adjusted to support the occupant in a reclining position.

Arranged on the under side of the chair, is a weight supporting bar 11,on which is slidably mounted a weight 12 which is adapted to be adjustedon the bar to hold the chair in an inclined or tilted position. Theweight 12 is held in its adjusted engagement with the bar 11 by a setscrew 13 or other suitable fastening device.

A chair constructed in accordance with my invention will be, at alltimes, supported in a level position, irrespective of the rocking orrolling motion of the ship, thus preventing sea-sickness. By revolublymounting the chair upon the base 1, said chair may be swung around inany direction. The provision of the adjustable weight 12 willcounter-balance the weight of the chair and hold the same in a tiltedposition, thus permitt-ingthe occupant to lean back or to.sit in anupright position.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claim.

Having thus described my invention, what I claim is:

In a chair of the class described, a supporting base, a frame revolublymounted thereon, said frame comprising an upright U-shaped member withits intermediate portion fixed to said base and having a substantiallycircular chair receiving member arranged at right angles and fixed tothe free ends of said U-shaped member, a series of open rings arrangedin said upper circular member of the supporting frame, means topivotally connect one of said rings with the circular member of saidframe, means to connect the other ring with the first mentioned ring atright angles to the pivotal l connection of the latter with the frame, achair arranged in said rings, and adjustable means to hold the chair intilted position.

In testimony whereof I have hereunto set 15 my hand in presence of twosubscribing witnesses.
